Extended Query Facilities for Racer and an Application to Software-Engineering Problems
نویسندگان
چکیده
This paper reports on a pragmatic query language for Racer. The abstract syntax and semantics of this query language is defined. Next, the practical relevance of this query language is shown, applying the query answering algorithms to the problem of consistency maintenance between object-oriented design models.

Development of a server to support the formal semantic web query language OWL-QL
In this abstract we present a server that supports OWL-QL query-answering dialogues by making use of the reasoning capabilities of the DL reasoner Racer. Currently, users can use Racer to query an OWL knowledge base using nRQL or DIG. Our primary goal in developing an OWL-QL server is to oer as many as possible reasoning functions of Racer in the standard query language OWL-QL. This rst version...
متن کاملInconsistency Detection between UML Models Using RACER and nRQL
An object-oriented software design consists of models that embody a consistent view on the software system under study. We focus on design models expressed in the Unified Modeling Language (UML) and more specifically on class, state machine and sequence diagrams. In this paper, we report on our experiences in using RACER and its New Racer Query Language (nRQL) for detecting inconsistencies betw...
متن کاملDiscovering Popular Clicks\' Pattern of Teen Users for Query Recommendation
Search engines are still the most important gates for information search in internet. In this regard, providing the best response in the shortest time possible to the user's request is still desired. Normally, search engines are designed for adults and few policies have been employed considering teen users. Teen users are more biased in clicking the results list than are adult users. This leads...
متن کاملOn-Line Nonlinear Dynamic Data Reconciliation Using Extended Kalman Filtering: Application to a Distillation Column and a CSTR
Extended Kalman Filtering (EKF) is a nonlinear dynamic data reconciliation (NDDR) method. One of its main advantages is its suitability for on-line applications. This paper presents an on-line NDDR method using EKF. It is implemented for two case studies, temperature measurements of a distillation column and concentration measurements of a CSTR. In each time step, random numbers with zero m...
متن کاملRacer: A Core Inference Engine for the Semantic Web
In this paper we describe Racer, which can be considered as a core inference engine for the semantic web. The Racer inference server offers two APIs that are already used by at least three different network clients, i.e., the ontology editor OilEd, the visualization tool RICE, and the ontology development environment Protege 2. The Racer server supports the standard DIG protocol via HTTP and a ...
